The cost of a train ticket increases by
erastova [34]

It costs $122.4 dollars before the increase.

<h3>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
  • Convert the problem to an equation using the percentage formula: P% * X = Y.
  • P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
  • Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Therefore, It costs $122.4 dollars before the increase.

galben [10]

Answer:

0.098

Step-by-step explanation:

Given that when filling out the 2000 Census, people could choose one of four options to describe their marital status.

Data from the 2000 Census were used to compute the following probabilities

Marital status Never married Married widowed Divorced total

Prob           0.239          0.595      0.068     0.098 1

Actually we were not given probability for divorced but using total probability =1 we arrived at the probability for divorced as

1-sum of the remaining probabilities

=1-0.239-0.535-0.068\\=0.098

the probability that a randomly selected U.S. adult is divorced

= 0.098

The number of mice tripled each year for the past 4 years in the small rural town. Which of the following characteristics best d
saul85 [17]

Answer:

The graph is a curved line that increases.

Step-by-step explanation:

If the mice triple in population every year then the population is increasing an at exponential rate by multiplying the previous mouse count by 3. I have included a image of a graph that would represent this.

Thus the graph is a curved line that increases, it is not a v shape because the population will constantly increase by 3 times each year, it is not a straight line because the mice population is not increasing in a linear fashion and the population is not U shaped as the population will not decrease as long as the mice population triples every year.

Hope this helps!
